{
features.Paging().Type(OpType.Local).PageSize(10).PageCountLimit(100).ShowPageSizeDropDown(true).ShowPagerRecordsLabel(true).PrevPageLabelText("Prev").RecordCountKey("totalRecords");

features.Sorting().Type(OpType.Local).ColumnSettings(settings =>
{
settings.ColumnSetting().ColumnKey("CustomerValue").AllowSorting(true);
settings.ColumnSetting().ColumnKey("Value").AllowSorting(false);
settings.ColumnSetting().ColumnKey("UserName").AllowSorting(false);
settings.ColumnSetting().ColumnKey("EditedDate").AllowSorting(false);
settings.ColumnSetting().ColumnKey("Action").AllowSorting(false);
});
features.Tooltips()
.Visibility(TooltipsVisibility.Overflow)
